Data Sheet AFBR-59E4APZ Multimode Small Form Factor (SFF) Transceiver for Fast Ethernet and FDDI, with LC Connector Description Features Multisourced 2 x 5 package style The AFBR-59E4APZ is a new power saving Small Form Operates with 62.5/125-m and 50/125-m multimode Factor transceiver that gives the system designer a product fiber to implement a range of solutions for multimode fiber Fast Single +3.3V power supply Ethernet. Wave solder and aqueous wash process compatibility This transceiver is supplied in the industry-standard 2 x 5 Manufactured in an ISO 9001 certified facility DIP style with an LC fiber connector interface. Compatible with the optical performance requirements of 100Base-FX version of IEEE 802.3u Compatible with the FDDI standard Transmitter RoHS compliant LVPECL Signal Detect Output The transmitter section of the AFBR-59E4APZ transceiver Temperature range: -40C to +85C utilizes a 1310-nm LED. This LED is packaged in the optical subassembly portion of the transmitter section. It is driven by an integrated circuit that converts differential LVPECL Application logical signals into an analog LED drive current. Fast Ethernet Receiver The receiver utilizes an InGaAs PIN photodiode coupled to a transimpedance preamplifier IC. It is packaged in the optical subassembly of the receiver. The PIN/preamplifier combination is connected to a quantizer IC, which provides the final pulse shaping for data output. The data output is differential LVPECL. The Signal Detect output is single- ended. Both Data and Signal Detect outputs are LVPECL compatible.
